I have 14.01 here. I also noted I no longer have an Adblock button to click on. Going to the Add-On page, selecting Adblock Plus (I have 2.1.2), and clicking Options gives me a blank page. That is, I'm still in Extensions, but there's nothing visible in Extensions. So, my Adblock Plus doesn't seem to be working, either.

After Firefox automatically updated to 15.0 today (which I didn't want), ABP no longer blocks ads. When right-clicking, there's not even an option to block something. It's as if ABP isn't installed at all.

I was having the same problem, the program updated a month or 2 ago and nothing worked since then, tried re subscribing to these filter lists, reinstalling etc. nothing worked.

Just because I'd run out of options I unchecked the "Disable everywhere" option in the add-on preferences page to see what it did, suddenly it works again? I assumed that this option meant disable ads, especially as it was checked by default when I installed the software, now i'm thinking it means disable the adbock software (why it even has this extra disable option is beyond me)

I had facebook open in a separate tab and the ads turned off and on as I was unchecking and checking that option.

so yeah, if someone else wants to give that a try and see if it gives the same results, it appears to have sorted my issues

i'm running firefox 17.0.1 on my ubuntu 12.04, i think there's a problem with adblock-plus add on, this add on not working properly as i try to click the Show in add-on bar checkbox and it's doesn't appear on my add-on bar, no matter what this function are correctly or not. the same problem also occur when i'm try to block some damn advertise with Adblock Plus:Block Image, Frame, etc.I had try to find any solutions on many forum, but there's no topics related to my issue. i hope i could get an update fix as soon as possible
